Sensor Fusion Tracking for Real-Time Player and Object Identification

The tracking system is divided into multiple independent active tracking devices, each equipped with sensors (accelerometers, gyroscopes, magnets) that independently track specific players or objects. This segmentation allows precise tracking of individual elements while distributing system complexity across multiple simple, standardized units rather than requiring one complex centralized system.

Active tracking devices are designed as universal units that can track any player or object in the sporting environment. Each device performs multiple functions including position tracking, motion detection, and data transmission, allowing the same hardware design to serve various tracking needs without requiring different specialized devices for different purposes.

Multiple active tracking devices continuously transmit tracking data at high sampling rates simultaneously, ensuring that tracking action is continuous and uninterrupted. This continuous data collection from multiple sources prevents data loss even if individual devices experience transmission issues, as other devices continue providing uninterrupted tracking information.

Data from multiple active tracking devices is merged and combined at a central processing system. By combining data streams from multiple devices tracking the same player or object, the system achieves high tracking accuracy through data fusion while maintaining continuous operation that prevents data loss, as the merged data compensates for any gaps in individual device transmissions.

The sensor fusion system is segmented into distinct functional modules: active tracking devices with sensors, passive tracking systems with cameras, and a central processing system. Each module performs a specific function independently, with the central system fusing data from both active and passive systems. This segmentation improves reliability by isolating failures to specific modules while maintaining overall system operation.

A central processing system acts as an intermediary between active tracking devices and passive tracking systems. This intermediary receives data from both system types, performs sensor fusion processing, and generates unified tracking output. The intermediary manages the complexity of integrating different sensor types and data formats, improving reliability by providing a centralized coordination point that ensures consistent data fusion while handling integration complexity in one location.
